The microscopic origin of line tension, used in the equilibrium description of liquid drops on flat surfaces, is not well understood. Simulations of water nanodroplets show that structural transitions ...
PARP inhibitors kill cancer cells by trapping poly(ADP-ribose) polymerase 1 (PARP1) on DNA. A study now shows that cancer cells use a specialized form of autophagy to extract and degrade trapped PARP1 ...
